Libnetwork has a default, built-in IPAM driver and allows third party IPAM drivers to be dynamically plugged. Docker controls the IP address assignment for network and endpoint interfaces via the IPAM driver(s). Why do you have to configure both 元 subnet and default gateway if macvlan promises to deliver an L2 network? Surely IP configuration of the containers in the macvlan network is dealt separately, either with the static configuration or by the external DHCP server?
Inet6 fe80::baae:deff:fead:beef/64 scope link Įth0 is up & running, it has both IPv4 and IPv6 address, so you’re good to go.Ĭreate a new macvlan network called macvlan0. You need to check if physical interface is up & running: # ip addr | grep 'mtu|inet'Ģ: eth0: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 List them with: # docker network lsĭocker macvlan network connects container interfaces with a parent, physical interface. sudo suīy default docker comes with some of the networks preconfigured. If you have no desire or means to provide native IPv6 connectivity, simply omit all IPv6 configurations which I kindly marked in italics.įirst, make sure you’re a root or have superuser permissions. Macvlan bridge mode allows you to configure the following topology:īeing IPv6 aware, all the configuration examples are dual-stack. While there are multiple macvlan modes, Docker macvlan driver only supports macvlan bridge mode. You should be fine with your updated Ubuntu. If you’re running RHEL (CentoOS, Scientific Linux, …) 6, you’re out of luck, upgrade to RHEL 7.
You can check your kernel version with uname -r. Last but not least, macvlan driver requires Linux Kernel 3.9 or greater. If you are looking for a production ready solution to connected your container into a physical Layer 2 network, you should stick to pipework for the time being.
#Docker for mac 1.11 how to
You can find more info on how to use the experimental build here. Important: As of Docker 1.11 macvlan network driver is part of Docker’s experimental build and is not available in the production release. If you are looking for a different network connection, refer to my docker network drivers post.īefore I begin, you should check some basics on what macvlan is, why it is a better alternative to a linux bridge and how it compares with ipvlan. You can connect the container into a physical Layer 2 network by using macvlan driver. If you are looking for a way to bridge the container into a physical network, you have come to the right place. Docker takes a slightly different approach with its network drivers, confusing new users which are familiar with general terms used by other virtualization products.
